Fish - The only way your going to know is giving it a go and seeing for yourself. You can always sell and go back to a 5'er.
That is exactly what we plan on doing. Our next camper will more than likely be a MH of some type. We have absolutely, positively no intentions of ever living full time in any camper but we do love to travel and camp. We've been at it for many years in Truck Campers, Travel Trailers and 5'ers. All three had advantages and disadvantages over the others. I suspect the same from a MH. We intend to find out for ourselves in a few years come retirement time.
I say give it a go.
